Question on Emm labs Dac6 vs Dac6e


I am considering to purchase a pre-owned Meitner separate, very much confused for the models, especially some has Dac6, some Dac6e, I know the latest are DAC 6e SE, can anyone tell me what is difference between Dac6 and 6e, is it significant as 6e to 6eSE?

between the dac6 and dac6e, i believe the original version used aes/ebu connections for all channels while the 6e included rca connections with the aes/ebu. i think the original version also had a small fan in it while the 6e did not. i'm not sure what changes were made from the 6e to 6e SE.
Kgturner is correct. The differences are the added RCA connections and one less fan. Some of them had rackmount ability and some did not. Sonically there is no difference.
I don't see a fan outlet at the back panel of the Dac6, is it just a small fan inside the unit like what we have on a computer cpu?
